And now for Something Completely... ON TOPIC!!!So, while I was waiting for the software to D/L (like FOREVER, for whatever reason) from the Hantek site, I decided to pop the top and peek inside...
A fairly Spartan BOM here; not much aside from the Cypress SOC and frontend ICs. I see cheap Chinese versions of the better machined-not-cast through-hole BNCs, and a tiny glued-on heat-sink on the 'scope section ADC. Rev. 1.01 dated 2013; doesn't appear much has changed from the original 2012 release version reviewed here:
https://www.eevblog.com/forum/testgear/hantek-6022be-20mhz-usb-dso/Even less to see on the bottom, aside from some pretty substantial redundant springs to ensure good grounding of the extruded case; I think the complaints I've read about the missing shield around the frontend are probably slightly paranoid.
One surprise is the LA probes: Cheapest possible version, but still proper dual-pincer "grabbit" style instead of cheapo J-hooks.
You get 9 each in yellow & blue, plus a couple in black. Cables are pretty short, and the usual cheap/stiff vinyl sheathed multicolor ribbon with individual 0.100"-header-style Amphenol FCI clone connectors.
Also a surprise is the internal construction of the LA grabbits; instead of a folded bit of cheap stamped tin they have a properly-sized square pin soldered to a bronze rivet holding the leaves of the grabbit fingers together. Huh.
Overall first impression: Excellent build quality for the money. If the software were as well-realized as this hardware, they'd never have attracted all the "whiny whiners whingeing" that seem to still haunt the brand's reputation.I'll followup with whatever basic tests I can manage considering I don't have any kind of a generator available short of the sound card in the laptop the 'scope will be connected to. I do think it might be very interesting to characterize the signal before & after something like my PAM8403 digital amplifier boards...
Cheers, and Merry Christmas!
